Peptide-containing liposomes, immunogenic liposomes and methods of preparation and use
First Claim
1. An immunizing dosage form which comprises an adjuvant liposome comprising:
- (i) a lipid which consists essentially of an organic acid derivative of a sterol; and
,(ii) an antigenic peptide,wherein the organic acid derivative of the sterol comprises an organic acid attached to the sterol at a hydroxyl of the sterol by an ether or ester linkage, wherein the organic acid is selected from the group consisting of carboxylic, dicarboxylic, polycarboxylic, hydroxy, amino and polyamino acids and wherein the liposome is present in the dosage form in an immunization dose.

Abstract
A high integrity liposome comprising at least one stabile lipid and at least one peptide-like therapeutic agent associated with the liposome, adapted for parenteral administration to an animal, including a human, and method according to manufacture and use.
Immunizing dosage forms comprising a liposome and an immunogen, wherein the liposome and immunogen are present in an immunization dose. Additionally, a dosage form, including such form particularly adapted to producing an immune response, comprising a salt according to an organic acid derivative of a sterol and an immunogen are present in an immunization dose, and method according to uses is disclosed. Further, a dosage form, including such form particularly adapted to producing an immune response, comprising dimyristolyphosphatidylcholine (DMPC)/cholesterol liposomes, optionally in an aluminum hydroxide gel, and an immunogen wherein the DMPC/cholesterol and immunogen are present in an immunization dose, and method according to use.
